Application filed December 5, 1923. Serial No. 678,761.

T 0 all whom it may] concern.

Be it known that I, ARTHUR P. PAINE, a citizen of the United States, residing at Worcester, in the county, of lVorcester and State of Massachusetts, have invented a new and useful Chain-Attaching Device for Yarn-Tube Frames, of which the following is a specification.

This invention relates to devices for'attaching a yarn tube frame to its transporting pattern chains in a loom. Such mechanism is largely used in Amninster carpet looms which in recent years have been manufactured in much wider sizes than has been heretofore customary. This increase in width has necessitated a corresponding increase in the length and weight of the tube frames which support the yarn spools and which deliver the tuft yarns between the warp threads. The increased weight and length of the tube frames has made desirable certain changes in the construction and operation of the attaching devices by which the tube frames are detachably secured to the pattern chains.

It is the general object of my invention to provide an improved construction. of frame attaching devices by means of which i the tube frames may be satisfactorily transported and which will be much less subject to displacement or breakage than the devices heretofore used.

With this object in view, I have provided a construction in which rigid attaching members are permanently secured to the transporting pattern chains and in which yielding co-operating members are provided preferably mounted in the tube frames in such positions that they are entirely enclosed thereby and are thus fully protected from accidental injury.

My, invention further relates to arrangements and combinations of parts which will.

i be hereinafter described and more particularly pointed out in the appended claims,

A preferred form of the invention is shown in the drawings, in which Fig. 1 is a front elevation, partly in section, of portions of a yarn tubeframe and its associated attaching devices;

Fig. 2 is a side elevation of the parts the chain and moved to weaving positlon,

shownin Fig. 1; I

Fig. 3 is a detail sectional plan view, taken along the line 33 in Fig. 1;

Fig. 1 is a perspective view of one end of a tube frame; and

Fig. 5 is a perspective view of a portion of the pattern chain.

Referring to the drawings, I have shown a tube frame which is in general of the usual type and comprises a rectangular tubular member 10 to which are secured a series of yarn tubes 11. A yarn spool 12 is supported in hearings in plates 13, each having its lower end bent to a substantially U-shape and providing a lower or inner bearing portion 14 for a purpose to be described.

An angle plate 15 is welded or otherwise secured to one side of the plate 13 and the portions 14 and 15 it closely within the member 10 and may be secured therein by screws 16 or in any other convenient manner. Flanges 17 project from the outer face of the plate 18 and at their outer ends are inwardly offset to provide guideways 18 for an attaching member 20 projecting downward from one of the links 21 of a trans porting pattern chain 22.

The lower end of the member 20 is provided with a rectangular opening 28 adapted to receive the end of a plunger or latch 24 when the tube frame is attached to the chain. The plunger 24: is slidable at one end in the bearing portion 1 4; of the plate 13 and at the other end in a rectangular opening in the plate 13 and angle plate 15. A spring 25 forces the plunger yieldingly outward and a cross pin 26 limits the out ward movement. The upper face of the plunger 24 is bevelled or inclined so that it will be yieldingly pressed inward when engaged by the bevelled lower end of the member 20, as the latter is inserted in the guideways 18.

With this construction it will be evident that the full insertion of the rigid members 20 in the guideways 18 will permit the latches 24 to operate automatically to firmly secure the parts together in such a manner that they cannot be accidentally displaced.

In order to separate the tube frame from the chain, a loom actuated clutch 26 usually found in this type of loom is provided for each end of the frame and is moved inwardly when a frame is to be taken from the support 27 passing under the. tube frame. A depressor 28 projects from the clutch and may be of any construction, shown herein forconvenience as an integral part of the clutch. The depressor is in alignment with the plunger 2 and serves to push the latter beyond the member 20, thus diconnecting the frame from the chain. To permit downward movement of the clutch and tube frame, the member 20 is provided with a slot 29 narrower than slot 23 and extending therefrom to the bottom of member 20, the depressor being so proportioned as to move freely down through slot 29.

All relatively moving parts are thus fully enclosed and protected within the tubular member 10 and the parts 20 may be of such strong and rigid construction that there is no probability of injury thereto.

Having thus described my invention and the advantages thereof, I do not wish to be limited to the details herein disclosed otherwise than as set forth in the claims, but what I claim is 1.. In a loom, transporting chains, a yarn tube frame, rigid attaching members permanently secured to said chains and extending therefrom, and yielding attaching members carried by said tube frame and co-operating with said rigid members to de tachably secure said tube frame to said chains.

2. In a loom, transporting chains, a. yarn tube frame, rigid attaching members permanently secured to said chains and extend' ing therefrom, and yielding attaching menr bers mounted in. said tube frame and movable therein to engage said rigid attaching members and detac hably secure said tube frame to said chains.

3. In a loom, transporting chains, a yarn tube frame, rigid attaching members permanently secured to said chains and extending therefrom, and yielding attaching members mounted in said tube frame and movable longitudinally of said tube frame, said yielding members engaging said rigid attaching members and detachably securing said tube frame to said chains. I I

4; In a loom, transporting chains. a yarn tube frame. rigid attaching members permanently secured to said chains and extending therefrom, and yielding attaching members carried by said tube frame and coopcrating with said rigid members to detachably secure said tube frame to said chains, said yielding members being entirely en closed and protected by said tube frame.

5. In aloom,transportingchains, a yarn tube frame, rigid attaching members permanently secured to said chains and extending therefrom. and yielding attachingmembers carried by said tube frame and co-operatin g with said rigid members to detachably secure said tube frame to said chains, said rigid members each having an opening adjacent its lower end and. said yielding members being movable trans versely across said openings to detachably secure said tube frame to said chains.

6. In a loom, transporting chains, rigid attaching members fixed to said chains and extending therefrom when in attaching position, a yarn tube frame having bearings therein, latches slidable in said bearings transversely of said rigid attaching members, a spring to more each latch yieldingly to operative holding position, and means to limit such yielding movement.

7. In a loom, a transporting chain, a yarn tube frame having an end socket. releasable interlocking connections between the chain and frame, said connections including a member rigid with the chain and extendinginto said frame socket, and a latch to hold said member in the socket.

8. In a loom, a transporting chain, a yarn tube frame having an end socket, releasable interlocking connections between the chain and frame, said connections includin a member fixed to the chain and extending into said frame socket, a latch to hold said member in the socket, and loom actuated means to releasesaid member from said latch.

9. In a loom, a transporting chain, a yarn tube frame having an end socket, releasable in erlocking connections between the chain and frame including a member formed with the chain and extending into said frame socket, a latch to hold said member in said socket, and loom actuated means to release said member from said latch.

10. In a loom. a. transporting chain, a yarn tube frame, releasable interlocking connections between the chain and frame including an element carried by the chain and extending toward the frame, a sprocket to engage said chain and position said element. yielding means carried by the frame to engage said element and hold the same, and means to more said tube frame toward and from said sprocket.

11. In a 100m. a transporting chain, a yarn tube frame having a t'ansverse guideway therein. a member secured to and extending from the chain and normally lying in said guideway, and yielding means to hold said member in said gnideway. said member having the portion adapted to enter the guideway tapered to facilitate entry into said gnideway.
